We reported a hypoglossal neurinoma located in the left submandibular region. A 69-year-old female visited our hospital with the chief complaint of a swelling of the left submandibular region. Paralysis and atrophy of the tongue were not exhibited. During the operation, it was recognized that the tumor was occurred in the left hypoglossal nerve anatomically and electrophysiologically. Intracapsular enucleation was performed as gently as possible. Post-operative hypoglossal nerve paralysis has not been observed immediately after surgery. Histopathological examination revealed neurinoma contained the Antoni A and B type. Postoperative course was uneventful until the time this report. Source

We reported a rare case of granular cell tumor of the vocal cord. A 57-year-old male visited our hospital with the chief complaint of hoarseness. Endoscopic examination revealed a yellowish and whitish mass in the inferior part of the right vocal cord with severe dysplasia of both vocal cords. The mass was excised by laryngomicrosurgery and diagnosed as a granular cell tumor. Postoperative course was uneventful. Source

A 42-and a 22-year-old females visited our hospital with the chief complaint of bilateral nasal obstruction. The smooth surface, milky and white colored elastic soft masses were located in the right nasal cavity of the case 1 and the left of the case 2. In each case, those tumors were successfully excised by endoscopic sinus surgery. Their origins were in the nasal septum in the case 1 and the lateral wall of the left nasal cavity in the case 2. Pathological diagnosis of each case was neurinoma. The postoperative courses of those cases were uneventful until the time of this report. Source

Purpose : To report a case of malignant lymphoma who showed ocular symptoms mimicking VogtKoyanagi-Harada (VKH) disease. Case : A 57-year-old male was referred for impaired visual acuity in both eyes. He had been diagnosed with VKH disease 4 weeks before. Pulse therapy with systemic corticosteroid was futile. He had received surgery for brain tumor 16 months before. Findings : Corrected visual acuity was 0.06 right and 0.2 left. Fluorescein angiography showed leakage and pooling of dye through the retinal pigment epithelium. Optical coherence tomography showed serous detachment. The findings were compatible with the diagnosis of VKH disease. Subtenon injection of triamcinolone acetonide and systemic cyclosporine resulted in improved visual acuity and persistent intraocular inflammation. It then became apparent that the brain tumor was malignant lymphoma. He started to show signs suggestive of tumor necrosis and died 7 weeks after his initial visit. Conclusion : This case illustrates that malignant lymphoma may masquerade as VKH disease and that due attention is needed to this possibility. Source

Using a tensor for total knee arthroplasty (TKA) designed to facilitate soft tissue balance measurements with a reduced patellofemoral joint, we intraoperatively compared the soft tissue tension of cruciate-retaining (CR) and posterior-stabilized (PS) TKAs performed at 0°, 10°, 45°, 90°, and 135° of flexion, with the patella both everted and reduced in 40 osteoarthritic patients. Although balance of soft tissue tension with a reduced patella of PS TKA slightly increased in varus from extension to flexion, these values slightly decreased for CR TKA from extension to flexion. Accordingly, we conclude that soft tissue tension patterns differ between everted and reduced patellae, as well as between PS and CR TKA. © 2011 Elsevier Inc. Source
